ATM SYSTEM

AIM:

To create a system to perform ATM banking transactions for the corresponding UML diagrams.

Problem statement:

This system is build for the client banking and managing process. The bank client must be able to deposital and withdrawal amount from

his/her accounts using the ATM machine. Each transaction must be recorded and the client must be able to review all transactions performed in his/her account. Recorded transactions must include the date, time, transaction type, amount and account balance after the transaction.

The bank manager is authorization to view the ATM machine status and its is the consolidated balance details of the ATM machine, today’s withdrawal, today’s balance and the limitations of the machine also appended.

The bank client is authenticated by login verification. If it is valid he/she will access their account otherwise an appropriate message is displayed to the client.

Software requirements:

Microsoft visual basic 6.0 is used as front-end for our project and ms-access is used as back-end to store the data.

USE-CASE diagram:

The ATM transaction use cases in our system are: 1. Login2. Withdraw3. Mini statement4. ATM machine status

5. Deposit

Actors involved:

1. User 2. Bank manager

USE-CASE name: Login

The user enters a user name and password. If it is valid, the user’s account becomes available. If it is invalid, an appropriate message is displayed to the user.

USE-CASE name: Withdraw

The user tries to withdraw an amount from his or her checking account. The amount is less than or equal to the checking account’s balance, the transaction is performed and the available information is displayed. The system creates a record of the transaction and the display confirmation message is displayed to the client.

USE-CASE name: Mini statement

The bank user requests a history of transactions for a checking account. The system displays the transaction history for the checking account. The transaction history consists of amount, date, transaction type and balance of the particular account.

USE-CASE name: ATM machine status

The bank manager enters a username and password. If it is valid, the bank manager accesses the machine status. If it is invalid, an appropriate message is displayed to the user.

USE-CASE name: Deposit

The bank user requests the system to deposit money to an account. The user accesses the account for which a deposit is going to be made and enters the amount. The system creates a record of the transaction and an appropriate confirmation message (display confirmation) is displayed to the client. The transaction must include the date, type, amount and account balance after the transaction.

DESCRIPTION:

Use-case diagrams graphically depict system behavior (use cases). These diagrams present a high level view of how the system is used as viewed from an outsider’s (actor’s) perspective

DESCRIPTION:The class diagram shows a set of classes, interfaces and collaboration and their

relationship. They are used for constructing executable system through forward and reserve engineering. Class diagram shows the attributes and operation of a class and constraints that apply to the way the object are connected.
